Patent number: 6626463Abstract: Provided is a seatbelt device capable of reliably securing and protecting a passenger. This seatbelt device has a first seatbelt tension increasing unit (9a) for increasing the tension of the seatbelt (4), and a second seatbelt tension increasing unit (9b, 20, 30) for increasing the tension of the seatbelt (4). When this seatbelt device judges that the collision of a vehicle is unavoidable, it operates the first seatbelt tension increasing unit (9a) before the collision and operates the second seatbelt tension increasing unit (9b, 20, 30) when it detects the collision of the vehicle. Thereby, the passenger is reliably secured to the seat and his/her safety is ensured.Type: GrantFiled: September 17, 1999Date of Patent: September 30, 2003Assignee: NSK Autoliv Co., Ltd.Inventors: Takashi Arima, Yukinori Midorikawa, Hiroshi Yamada, Katsuyasu Ono

Publication number: 20030173131Abstract: An automotive passenger restraint and protection apparatus for an automotive vehicle has a seatbelt and operates to restrain an occupant of the automotive vehicle by the seatbelt to protect the occupant. An electric retractor has a DC motor for retracting and protracting the seatbelt. An MPU applies voltage having a predetermined waveform to the DC motor, and then detects a waveform of current flowing to the DC motor. The MPU carries out fault diagnosis of the DC motor, based upon the detected waveform of current when the voltage having the predetermined waveform is applied to the DC motor. Thus, accurate fault diagnosis of the apparatus can be achieved.Type: ApplicationFiled: March 11, 2003Publication date: September 18, 2003Applicant: NSK AUTOLIV CO., LTD.Inventors: Yukinori Midorikawa, Osamu Kawai

Patent number: 6616186Abstract: A seatbelt device which prevents an occupant from hitting his face against an airbag deploying at the time of a vehicle collision. In order to take up any seatbelt slack before a collision and prevent the occupant from being displaced forward, the seatbelt device comprises a first tension modifier for winding the seatbelt and taking up the seatbelt slack when a collision is predicted, and a second tension modifier for further enhancing the tension of the seatbelt and securing the occupant to the seat at the time of such collision, thereby ensuring that the occupant does not exist in the airbag deployment zone when the airbag is activated.Type: GrantFiled: September 7, 2000Date of Patent: September 9, 2003Assignee: NSK Autoliv Co., Ltd.Inventors: Yukinori Midorikawa, Hiroshi Yamada
